Question

Q27. The SI unit of young's modulus of
elasticity is​

Answer 1

Answer:

Young's modulus = stress/strain = (FL0)/A(Ln − L0). This is a specific form of Hooke's law of elasticity. The units of Young's modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m2).

Answer 2

Answer:

Elastic modulus = change in stress (in Pascals) / change in strain (in dimensionless units (= m/m))

Step-by-step explanation:

Youngs modulus = stress / strain

Stress = Force /Area

Strain = change in length/original length

Stress has dimension [ ML-¹ T-²]

Strain = dimensionless

So dimension of Young's modulus is

[ML-¹ T-²]
